The constant element (macroelement) refers to the percentage of weight more than 0.01% of the organic elements in the body content. A larger proportion of these elements are accounted for in vivo, organism needs more. Is the essential elements of the organism.
Major elements Plant
Plants need large amount of elements from water and atmosphere
Carbon, hydrogen, oxygen, and from soil or fertilizer supplements such as nitrogen, phosphorus and potassium, calcium, magnesium, sulfur and other elements. In Solution culture
When cultured in the content should be higher. As the plants need nitrogen per gram dry weight 1000 Mole
Carbon, hydrogen and oxygen, 3000 6000 mol, 30 mol% of sulfur. trace element
Nitrogen is only 7 micromolar, molybdenum only 0.014 micromolar.
Major elements human body
The human body contains 60 kinds of elements that are essential for maintaining normal physiological function of the elements, known as essential elements, a total of 20 kinds, the body content of more carbon, hydrogen and oxygen, nitrogen, phosphorus, chlorine, sodium, magnesium, potassium, calcium, about 99.9% of the body weight, the essential elements of life in addition, carbon, hydrogen, oxygen, nitrogen mainly existed in the form of organic substances, the remaining elements are inorganic minerals. The mineral elements in the human body, all content is greater than 0.01%, is called a constant elements, calcium, phosphorus and potassium, sulfur, magnesium chloride, 7.
The standard of healthy adults elements 65%, 18% carbon, oxygen, nitrogen, calcium hydrogen 10% 3% 1.5%, 1% phosphorus, potassium 0.35%, sulfur 0.25%, 0.15% sodium chloride, 0.15% mg, 0.05%. The 11 kinds of content are more than 0.01% elements are called human elements. These major elements account for about 99.9% of body weight.
All of the major elements of the human body, carbon, hydrogen and oxygen, nitrogen is the main element of the composition of the human organic matter, accounting for more than 96% of the total weight of the body.
Major elements Effect
N N Calcium Ca
Calcium accounted for about 1.7% of body weight, with 99% hydroxyl groups phosphoric acid
Calcium exists in the bones and teeth, 1% in the blood. Ion
State calcium can promote the prothrombin into thrombin, the wound blood coagulation. Calcium plays an important role in many physiological processes, such as in the telescopic movement of the muscle, it can be activated ATP enzyme
The body, maintain the normal movement. Children suffering from rickets may be calcium deficiency in elderly; Osteoporosis
(hyperosteogeny); easy bleeding injury. Calcium is good sedative, it helps to convey nerve stimulation, nerve relaxation, it can make you easy to sleep instead of sleeping pills, calcium nerve becomes tense, irritable and insomnia. Calcium also reduced Cells
The permeability of the membrane, prevent harmful bacteria, virus or allergens into cells. Calcium is a good analgesic that can help you reduce fatigue and accelerate recovery of energy. Adults need calcium recommended value of 1 grams / day or more. Milk and milk products is an ideal source of calcium, in addition to Huang Yucan, sea cucumber, sesame, beans, shrimp, cheese, wheat, soybean, mustard, honey is rich in calcium. The amount of Vitamin D
3 and P is conducive to calcium absorption. Glucose
Acid and calcium lactic acid
Calcium easily absorbed, is the ideal calcium supplement tablets. P P
The content of phosphorus in the adult body is about 700 grams, 80% in insoluble phosphate
The deposition in the form of bones and teeth, the rest mainly in Intracellular fluid
In. It is the largest anion content in the fluid inside the cell, is a bone, nucleic acid
The basic components, both in vivo metabolism of muscle during storage and energy release material, is the main buffer cells. Phosphorus deficiency and excessive intake of phosphorus will affect the absorption of calcium, calcium will also affect the absorption of phosphorus. The daily intake of calcium and phosphorus ratio of Ca/P = 1 ~ 1.5, is conducive to the absorption. Normal diet is generally not P. Magnesium Mg
The content of magnesium in the body weight is about 0.05%, it is one of the essential biological nutrient elements. The human body in 50% magnesium deposition in the bone, then in the interior of the cell, only 2% in the blood, magnesium and calcium as a protective effect, is a good sedative, severe magnesium deficiency, makes the brain's confusion, loss of sense of direction, hallucinations and even insanity. Magnesium is lower blood Cholesterol
The main Catalyzer
Again, to prevent atherosclerosis
Therefore, adequate intake of magnesium, can prevent heart disease. It is the activator and magnesium in mammalian animal enzymes. Every cell in the human body needs it for magnesium. Protein
The synthesis of, Fat
Use and sugar and hundreds of groups Enzyme system
Have an important role. Because most enzymes contain VB6, VB6 and must be combined with magnesium, can be fully absorbed and utilized; lack of one will appear cramps, tremors, insomnia, nephritis and other symptoms, so magnesium and VB6 with treatment of epilepsy. The ratio of magnesium and calcium properly, can help the absorption of calcium, the proper ratio of Mg/Ca=0.4 to 0.5. If the lack of magnesium, calcium with loss of urine, if the lack of magnesium and calcium and phosphorus is VB6, will form a stone (stone, Renal calculus
And bladder lithiasis), these stones are insoluble calcium phosphate, which is why arteriosclerosis. Magnesium is a diuretic and laxative. If it will lead to excessive magnesium, magnesium and calcium and phosphorus from Faeces
And the loss of a large number of urine, causing muscle weakness, dizziness, nausea, loss of sense of direction, slow heartbeat, vomiting and loss of consciousness. So the calcium, magnesium and phosphorus intake should be appropriate, proportionate, can ensure your health and longevity. Is the best source of magnesium Nut
Soybean, and Green vegetables
. Men need more magnesium than women. Sodium, potassium, chlorine and sulfur
Na, K, Cl S
Sodium, potassium and chlorine are macro elements in the human body, which accounted for 0.15% of body weight, 0.35%, 0.15%, potassium mainly exists in intracellular fluid and sodium in Extracellular fluid
In. And chlorine in the inside and outside of cells in body fluids are. These three substances can make the fluid to maintain neutrality. The amount of water determines the organization; Na+ in vivo from the sodium pump function, regulation osmotic pressure
Water transportation, to the body, makes the nutrient from the intestine into the blood by the blood into the cell; potassium helps nervous system
Convey information; chlorine
For the formation of gastric acid. The three substances every day with urine, sweat, intake and excretion of healthy people every day are roughly the same, which of these three substances basically unchanged in vivo content. Potassium is mainly composed of fruits and vegetables, meat, food supply, and sodium and chlorine by salt
Supply. Potassium and sodium in the body must balance each other, too much sodium potassium will make the urine loss, excessive potassium sodium will also cause serious loss. Sodium can promote blood pressure, therefore, excess sodium intake will suffer from hypertension, and hereditary. Potassium can activate a variety of enzyme
, on the contraction of muscle is very important, no potassium, sugar will not be transformed into existence in glycogen energy storage (or for The new supersedes the old
The energy provider, the muscles can not flex) can cause numbness or paralysis. In addition the intracellular and extracellular potassium sodium, can form a balanced state under normal circumstances, when the lack of potassium, sodium will bring a lot of water into the cells so that the cell expansion, the formation of edema. Potassium deficiency can lead to reduced blood glucose. Not enough magnesium will make potassium excretion, and out of cells, causing the cells to produce potassium deficiency, cardiac arrest. stay U.S.A
A survey found that people under the age of 50 sudden death from heart disease is myocardial cells due to potassium deficiency, therefore potassium, sodium and magnesium and calcium intake should be balanced, in order to ensure a healthy body.
